The cornerstone of modern peptide purification is chromatography. Among the various chromatographic approaches, Reverse-phase chromatography (RPC), often implemented as High-performance liquid chromatography (HPLC), stands out as the most versatile and widely adopted methodPurificationof biomolecules from complex feeds, i.e., crude recombinantpeptides, is often best carried out using combinations of orthogonal separationmethods.... This technique leverages hydrophobic interactions between the peptide molecules and a non-polar stationary phase (commonly C18-modified silica). By employing a mobile phase that gradually increases in organic solvent concentration (a process known as gradient elution), peptides can be effectively separated based on their hydrophobicity. This approach is particularly adept at separating target peptides from truncated or incompletely synthesized variants, a common challenge in peptide synthesis.

Within the realm of RP-HPLC, different modes of operation exist to cater to specific purification needs. Preparative or semi-preparative HPLC is frequently utilized for purifying larger quantities of peptidesReversed-phase liquid chromatographyis the most popular method for peptide purification and is ideal for separating target peptides from truncated or branching ....

Beyond RP-HPLC, other chromatographic techniques offer complementary separation mechanisms. Ion-exchange chromatography (IEX) is another valuable tool, particularly useful for separating peptides based on their net charge. This method is especially relevant when dealing with peptides that exhibit significant charge differences, making it an excellent orthogonal purification strategy when combined with RP-HPLC.
